Royal One Ball

one-ball games

One-ball games came before the in-line bingo's, and
the name is literal. After depositing coins to determine
payout odds and features, the player shot one ball to
determine the winner.

There were a few one-ball games made with five
balls. The first four balls would be shot into a channel
on the left top of the playfield by "skill", thus
qualifying the fifth ball to be used to roll around the
playfield and drop into a hole to determine win/lose.

The skill consisted of pulling the ball shooter all the
way back and letting it go. Of course, the whole point
was to try and convince the law that the game was not
a gambling device, but required actual player talent to
determine the outcome.
